<p>Let&#39;s use Fig to set up and run a Django/PostgreSQL app. Before starting, you&#39;ll need to have <a href="install.html">Fig installed</a>.</p>
<p>Let&#39;s set up the three files that&#39;ll get us started. First, our app is going to be running inside a Docker container which contains all of its dependencies. We can define what goes inside that Docker container using a file called <code>Dockerfile</code>. It&#39;ll contain this to start with:</p>
<div class="highlight"><pre><code class="text language-text" data-lang="text">FROM orchardup/python:2.7
<div class="highlight"><pre><code class="text language-text" data-lang="text">FROM python:2.7
ENV PYTHONUNBUFFERED 1
RUN apt-get update -qq &amp;&amp; apt-get install -y python-psycopg2
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/

<p>Second, we define our Python dependencies in a file called <code>requirements.txt</code>:</p>
<div class="highlight"><pre><code class="text language-text" data-lang="text">Django
psycopg2
</code></pre></div>
<p>Simple enough. Finally, this is all tied together with a file called <code>fig.yml</code>. It describes the services that our app comprises of (a web server and database), what Docker images they use, how they link together, what volumes will be mounted inside the containers and what ports they expose.</p>
<div class="highlight"><pre><code class="text language-text" data-lang="text">db:
